Folding – BL Shutters

Folding
High Speed Folding Doors

Engineered for Extra-Large Openings & Maximum Wind Resistance
BL Shutters’ Folding High-Speed Doors are purpose-built for large-scale external openings where durability, speed, and wind stability are critical. These robust doors are ideal for use in logistics centres, warehouses, transport depots, and industrial buildings in wind-exposed or high-traffic environments.
Capable of withstanding wind loads up to Wind Class 5 (equivalent to wind speeds exceeding 100 km/h), these doors are among the strongest in the market — ensuring reliable operation and protection even in the most extreme conditions.
